y e a can. (ci. :ts-ss) This invention relates to alarm clocks. and

Another object of this invention isto provide an improved alarm clockin which a plurality o! separate organized alarm-units are all moimted on a. single unitary base. n y Another object of this invention is to provide an improved alarm clock having separate organized alarm-units. all carried by a case-back or back-plate of an alarm clock.

Another object of this invention is to provide an improved alarm clock having a main movement including a time-train. a main alarm-train.

and driving-means and` supporting-structure therefor, all organized as a main unit, together with a secondary movement including a secondary alann-train and driving-means and supporting-structure therefor, `all organized asta secondary unit, with release and shut-off mechanism mounted on the main unit and having a secondary alarm-release and shut-oi! extension extended to the secondary unit. l l

With the above and other objects in view. this invention includes all improvements over the prior art which are disclosedin this application.

In the accompanying drawing, in wbichione way of carrying out the invention is shown for illustrative purposes:

broken away, of an alarm clock made `in accordance with this invention; e

Fig. 2 is a iront elevation of the main and secondary movements mounted on the oase-back and with the dial and hands omitted;

Fig. 3 is a perspective view of the alarm-release and shut-oir member ior both the main and secondary alarms and Fig. 4 is an enlargedA fragments] elevation of the alarm-control mechanism. e

In the description and claims, the various parts are identined by specific names ior convenience. but they are intended to be as generic in their application as the prior art will permit.

Referring to the drawing, Il is vs. clock-case having a base Il and a, removable case-back or back-plate I2. A main movement Il includes iront and rear movement-plates Il and Il connected by the tour pillars Il, which latter are 55 clampedtothecase-backbetweentheinner Fig. 1 is an edge elevation with the case partly nuts I1 .and the outer nuts il and `washers Il. The main movement Il has a usual time-train 20 driven by a usual mainspring 2i and a main alarm-train 22 driven bya main alarm-spring 23. The bell or sounding-member 24 is adapted to be actuated by a hammer 2! carried by or `formed -ona hammer-arm 2l pivoted at 21 in the iront and rear movement-plates Il and i5.

t 'I'he hammer-arm 26 has formed thereon or secured thereto a verge 28 actuated by thevergewheel 29 of the alarm-train 22.- The hammertail or nger Il is formed on or secured to the hammer-arm 20 and vibrates or oscillates when tue hammer 25 is oscillating in its movement of striking the bell 2l. 'Ihe hammer-tail 3B is adapted to be engaged by a stop-unser Il formed on or secured to the alarm-release and shut-oil arm 32.l which is preferably formed of springmetal, such, for example, as spring-brass. and is firmly secured to the iront movement-plate Ill by the riveted end of the stud Il which extends through the aperture 34 in the alarm-release and shut-oil arm I2, to which stud the mainspring 2| is anchored. -The arm 32 has an aperture 35 slidably engaging the `alarm-sei; stai! 36.

'An L-shaped alarm-shut-ofi lever I1 is pivoted be means of a screw I8 to a bracket I! secured to the iront movement-plate Il. A manual or nnger-shut-on lever 40 is pivoted at Il to a bracket l2 clamped between one ot the nuts i1 and the case-back i2. The iinger-shut-oi! I0 has a reach l! adapted to engage the end Il of the lever 31 when the shut-oi! I0 is moved to the position shown in solid lines in Fig. 1, to swing the control-end 4I of the lever 81 down into engagement with the arm I2 to yieldabiy press the latter downward to bring the stop-nnger 3i into engagement with the hammer-tail Il. thus serving to hold the hammer locked against oscillation. When the finger-shut-oi! 4l is moved to the dotted-line position shown in Fig. 1, the spring-arm I2 is released. whereupon the movements of the arm I2 are controlled by the alarmcontrol cam Il. the alarm-control nnger 41 and the alarm-set stai! Il, as will be hereinafter dederIl,vrlilclicylinderisplvoteliatoneendintbearing 54 in the base 48, and at its opposite end is pivoted in a downward extension of the bracket /51, which latter is secured by screws` to the --f-base 4s.

A winding-arboril has a winding-key 58 and is pivotally mounted at 59 ln the base 48 and at 6b in the bracket 5L An alarm-spring 6I has one end secured at 62 to the downwardly-extending finger 63 of the bracket 55, and has itsother end secured to the Winding-arbor 51, which latter also has secured thereto a pawl 64 adapted to engage the ratchet-teeth 651 formed on one side of a gear 66 frotatably mounted on the winding-arbor 51. v

Thegear 66 meshes with and drives a gear 61` secured to the cylinder 53. Also secured to the cylinder 53 is a large speed-control `gear 68 which meshes with a small gear' 69 which latter is rigidly connected `with a larger gear 10,\t'he latter and has a guide-hole 16 slidably engaging 'a pin 11 secured to the front movement-plate I4.` The extension has a downwardly-bent end 18 adapted, when inthe full-line position shown in Fig. 1, to engage and lock the air-vane 14, and when in the partially-raised dotted-line position indicated in Fig. 1, to release the `air-vane 14, and Whenin the fully-raised dotted-line position indicated in Fig.

1, to release both the air-vane 14` and the hammer-tail 30, as will be morefully hereinafter explained. i l In operation, by `means of the alarm-set sta 36, the alarm-mechanism can bel-set for any desired time of operation, in the usual manner. When the gear 19, to which the alarm-control camg46 is secured, rotates the cam 46 to bring the notch `lil opposite the alarm-control finger 41, the spring-arm 32 pushes the gear 19 and cam 46 axially of the staff36 until stopped by the base of the notch 80,1this movement permitting the arm 32 to rise suiiciently to bring the end 18 to the Vintermediate dotted-line position sufilciently far above the butterfly control-vane 14 to release the latter, whereupon the spring 6|, through the mechanism described, causes the cylinder 53 to rotate, with the result that the pins `52`1lft the musical spring-fingers 5t and release thesame with a snap release, whereby the fingers vibrate to produce musical tones which may be in accordance with any pattern or tune desired, depending Y upon the number and arrangement of the pins52 32 pushes the gear 19 and1cam`46 still further until the bottom of the notch 8i is reached, thus permitting the arm 32 to rise to the fully-raised dotted-line position sumciently high to cause the finger 3| `to rise out of engagement with theham-` 5 mer-tail thus resultingin the hammer 25being oscillated in the usualmanner by the main alarm-train to actuate the main or loud sounding-member 24. t i

As the time-train continues to rotate the gear l0 19 and cam 46, the control-finger 41 finally rides up the incline 82 of the cam 46 and resultsV in the all changes coming within the meaning and equiv- 25 alency range of the appended claims are intended to be embraced therein. i

I claim: t 1. An alarm-clock construction including: a main movementincluding a `time-train, la main 39 alarm-train, and driving-means and supporting-l structure therefor, allorganized as a main unit; a secondary movement :including a secondary alarm-train, and driving-means and supporting.- i

structure therefor, alllorganized as a secondary unit; a main alarm-release and shut-offspringarm mounted on the main unit and having asecondary alarm-release andV shut-off extension carried by and rigid withsaid shut-off arm and extended to the `secondary unit and "adapted`to40 first `release said secondary alarm-train and` to later release said 'main alarm-train; means adapted to partially release said arm -to first release said secondary alarm-train and later to further release said arm to later release said main alarmtrain; and guide-means mounted on said main unit and slidably engaging` and guiding said springarm.

2. An alarm-clock construction including: a e main movement including a time-train, a main alarm-train, and driving-means and supportingstructure therefor, all organized as a main unit; i a` secondary movement including a secondary alarm-train, and driving-means and supportingi structure therefor, allorganized as a secondary 5;

unit; and a main alarm-release and shut-off arm mounted on the mainunit and having a secondary alarm-release and shut-off extension carried by and rigid with saidshut-oft arm and extended to the secondary unit,and means adapted` to par- 69 tially release said arm to first release said secondary alarm-train and later to further release said arm `to later release said main alarm-train.
